Pehea e koho ai i ka transducer pono no ka ULTRASOUND SCANNER?

Ka pono o kamea ʻimi ʻiminui ka hilinaʻi ʻana i nā mea kani ultrasound i hoʻokomo ʻia i loko.Hiki i kā lākou helu i loko o ka mea scan hoʻokahi a hiki i 30 mau ʻāpana.He aha nā mea ʻike, he aha ia a pehea e koho pono ai iā lākou - e nānā pono kākou.

NA ANO O NA SENSO ULTRASONIC:

• hoʻohana ʻia nā ʻimi linear no ka nānā ʻana i nā ʻano pāpaʻu a me nā kino.ʻO ka alapine e hana ai lākou he 7.5 MHz;
• hoʻohana ʻia ka ʻimi convex no ka ʻike ʻana i nā ʻiʻo a me nā ʻāpana hohonu.Aia ka alapine (frequency) e hana ai ia mau mea ike ma loko o 2.5–5 MHz;
• nā mea ʻike microconvex - ʻo ke ʻano o kā lākou noi a me ke alapine e hana ai lākou e like me nā ʻano mua ʻelua;
• nā mea ʻike intracavitary - hoʻohana ʻia no ka transvaginal a me nā haʻawina intracavitary ʻē aʻe.ʻO 5 MHz kā lākou scanning frequency, i kekahi manawa kiʻekiʻe;
• hoʻohana nui ʻia nā mea ʻike biplane no nā diagnostics transvaginal;
• hoʻohana ʻia nā mea ʻike intraoperative (convex, neurosurgical a me ka laparoscopic) i ka wā o nā hana ʻoki;
• nā mea ʻike invasive - hoʻohana ʻia e ʻike i nā kīʻaha koko;
• nā mea ʻike maka (convex a i ʻole sectoral) - hoʻohana ʻia i ke aʻo ʻana i ka pōkā maka.Hana lākou ma ke alapine o 10 MHz a i ʻole.

KE KUMU O KE KOHO I NA SENSO NO KA ULTRASOUND SCANNER

Nui nā ʻano like ʻolenā kani kani ultrasonic.Koho ʻia lākou ma muli o ka noi.Hoʻomaopopo pū ʻia ka makahiki o ke kumuhana.Eia kekahi laʻana, kūpono nā meaʻike 3.5 MHz no nā mākua, a no nā maʻi liʻiliʻi, hoʻohanaʻia nā meaʻike o keʻano hoʻokahi, akā me ke alapine hana kiʻekiʻe - mai ka 5 MHz.No ka ʻike kikoʻī o nā pathologies o ka lolo o nā pēpē hou, hoʻohana ʻia nā mea ʻike ʻāpana e hana ana ma ke alapine o 5 MHz, a i ʻole nā ​​​​mea ʻike microconvex kiʻekiʻe.

No ke aʻo ʻana i nā ʻōpū o loko i hohonu, hoʻohana ʻia nā mea ʻike ultrasound, e hana ana ma ke alapine o 2.5 MHz, a no nā hale pāpaʻu, pono ke alapine ma kahi o 7.5 MHz.

Hana ʻia nā hoʻokolohua naʻau me ka hoʻohana ʻana i nā sensor ultrasonic i hoʻolako ʻia me kahi antenna phased a hana ʻia ma ke alapine a hiki i 5 MHz.No ka ʻike ʻana i ka naʻau, hoʻohana ʻia nā mea ʻike i hoʻokomo ʻia ma o ka esophagus.

Hana ʻia ke aʻo ʻana o ka lolo a me nā hoʻokolohua transcranial me ka hoʻohana ʻana i nā mea ʻike, ʻo ke alapine hana ʻo ia ka 2 MHz.Hoʻohana ʻia nā mea kani kani e nānā i nā maxillary sinuses, me ke alapine kiʻekiʻe - a hiki i 3 MHz.
